Azure Node.js Web应用程序的自定义启动命令(ES2015/babel)? [英] Custom start-up command for Azure Node.js Web app (ES2015/babel)?

问题描述

我正在将ES2015 node.js应用程序从Heroku迁移到Azure.

I am migrating an ES2015 node.js application from Heroku to Azure.

在Heroku上运行的当前启动命令是

The current start-up command running on Heroku is

"start": "./node_modules/babel-cli/bin/babel-node.js index.js"

但是，在Azure上，我得到了

However, on Azure I am getting

package.json中的无效启动命令"./node_modules/babel-cli/bin/babel-node.js index.js".请使用格式节点<脚本相对路径>".

Invalid start-up command "./node_modules/babel-cli/bin/babel-node.js index.js" in package.json. Please use the format "node <script relative path>".

这表示Azure仅支持npm start的香草节点.

Which indicates that Azure only supports vanilla node for npm start.

我知道在生产环境中运行babel-node并不理想，但是我希望进行直接迁移.

I'm aware that running babel-node on production isn't ideal, but I was hoping for a straightforward migration.

需要一些重新架构的三个选项是:

Three options that would require a bit of re-architecting are:

1. 使用gulp工作流程预编译ES2015: https://github.com/christopheranderson/azure-node-es2015-example
2. 使用bash工作流预编译ES2015:

1. Using a gulp workflow to precompile ES2015: https://github.com/christopheranderson/azure-node-es2015-example
2. Using a bash workflow to precompile ES2015: http://www.wintellect.com/devcenter/dbaskin/deploying-an-es6-jspm-nodejs-application-to-azure
3. Using babel-register ala [link in comments].

我怀疑选项3将是最简单的方法，但是检查是否有人遇到类似问题并设法在Azure的npm start中直接运行babel-node.

I suspect option 3 will be easiest but checking if anyone has come across a similar issue and managed to run babel-node directly in npm start on Azure.

推荐答案

根据您的问题，请在Azure Web Apps上将start npm脚本修改为node ./node_modules/babel-cli/bin/babel-node.js index.js.

According your issue, please modify your start npm script to node ./node_modules/babel-cli/bin/babel-node.js index.js on Azure Web Apps.

这是测试package.json中的内容:

{
  "name": "website",
  "description": "A basic website",
  "version": "1.0.0",
  "engines": {
    "node": "5.9.1",
    "npm": "3.7.3"
  },
  "scripts": {
    "start": "node ./node_modules/babel-cli/bin/babel-node.js index.js"
  },
  "dependencies": {
    "babel-preset-es2015": "^6.6.0",
    "babel-cli": "^6.0.0"
  }
}

同时，如果需要更高版本的Node.js，则可以在package.json中指定，请参考

Meanwhile if you need a higher Node.js version, you can specify in package.json, refer to https://azure.microsoft.com/en-us/documentation/articles/nodejs-specify-node-version-azure-apps/ for more.
